[A woman in her thirties with frequent mucosal ulcers].

Background: Haploinsuffiency A20 (HA20) was first described in 2016 and is caused by a mutation in TNFAIP3/A20. Non-related families living on different continents were examined with whole exome sequencing (WES). All had symptoms of Behçet's disease.

Quantification of microplastics in wastewater systems of German industrial parks and their wastewater treatment plants.

Microplastics (MP) enter the aquatic environment via several pathways. Many research groups have focused on municipal discharge, while research on industrial sources is rare. This study provides one of the first insights into MP occurrence and distribution in the wastewater systems of industrial parks (IPs) and their wastewater treatment plants (IPWWTPs).

Semi-crystalline microplastics in wastewater plant effluents and removal efficiencies of post-treatment filtration systems.

Microplastics (MPs) are ubiquitous in the environment and have been found in every environmental compartment. Wastewater and wastewater treatment plants (WWTPs) have been identified as possible point sources contributing to the emission of microplastic particles (MPP) into the aquatic environment. So far, MPP in wastewater effluents have mainly been analyzed by spectroscopic methods resulting in concentrations as number per volume.

A sustainable and efficient recycling strategy of feather waste into keratin peptides with antimicrobial activity.

The study aimed to propose an efficient and eco-friendly strategy to improve the utilization of feather waste and converting it into high-valued antimicrobial products. Under the synergistic effect of instant catapult steam explosion (ICSE) (1.5 MPa-120 s), over 90% of chicken feather powder (CFP) was degraded into soluble peptides via keratinolysis within 3 h, about 90% of which were smaller than 3 kDa, indicating an overwhelming advantage than general proteolysis.
